The thing is, Styrofoam isn't meant to be eaten, and for good reason. It's not like a chocolate chip cookie or a crunchy potato chip that your body can digest and turn into energy. Instead, it's more like trying to digest a plastic bag or a synthetic fiber, which just doesn't compute.
Imagine putting a piece of Styrofoam in a blender and hitting puree. What would you get? A weird, fluffy mess that's still not edible, right? It's kind of like that when your body tries to break down Styrofoam - it just can't do it, and that's when problems start to arise.
